MAILING-WRAPPER.

SPECIFICATION forming' part of Letters Patent No. 673,471, dated May 7, 1901.

Application iiled December 24, 1900. Serial No. 40,949. (No modele To all whom, t may concern,.-

Be it known that I, MARY CARROLL MC- CORD, a citizen of the United States, residing at Balm, in the county of Mercer and State of Pennsylvania, have invented a new and useful Mailing-Wrapper, of which the following is a specification.

Thisinvention relates to mailing-wrappers, and has for its object to provide an improved device of this character which is formed so as to clearly indicate that the wrapper has been opened or tampered with and also arranged to facilitate the opening thereof without damage to the contents of the wrapper. It is furthermore designed to arrange for inclosing a letter or the like and a register-card within the same wrapper, so as to transmit the two simultaneously and also to facilitate the insertion of the letter and the cards into the respective parts of the wrapper.

With these and other objects in View the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings,and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure 1 is a plan View of the main blank from which the present mailing-wrapper is formed. Fig. 2 is a similar view showing the blank folded so as to form two pockets or envelops. Fig.A 3 is plan View of the pockets or envelops folded and provided with the sealing-strip. Fig. 4 is an edge elevation illustrating the manner of inserting one of the envelops into the other prior to finally sealing the wrapper. Fig. 5 is a perspective view of the Wrapper when sealed.

Like characters of reference designate corresponding parts in all of the iigures of the drawings.

Referring particularly to Fig. 1 of the drawings, it will be seen that the main blank of the wrapper comprises the opposite rectan gular sections l and 2, as indicated by dotted lines,the sections being preferably oblong and arranged end for end. One of the sectionsas, for instance, the section 2-is slightly wider than the other, for a purpose as will be hereinafter explained. Each section has the opposite longitudinal flaps 3 and 4, respectively, and the outer end flaps 5 and 6.

As indicated in Fig. 2, the respective pairs of side flaps are folded over upon the same sides of the sections and sealed or otherwise connected, it being understood that the flaps are slightly wider than onefhalf ot` the width of the section in order that said flaps may overlap to be sealed, preferably With some adhesive material, as employed iu the manufacture of envelops. The side flaps'are folded `along the respective longitudinal dot-ted lines, so that the envelop 2 is wider than the envelop 1. The respective end flaps are then folded over upon the side aps and sealed, thereby cornpleting the two envelops, which have their inner adjacent ends only open for the reception of letters or other matter to be iuclosed. After the envelops have thus been formed they are then folded back to back upon the flexible connection between their inner ends formed by the material from which the envelops are made, thereby leaving the said inner and adjacent ends of the envelops open and unobstructed. A sealing-strip 7 is then applied to the outer side of the larger envelop 2, as indicated in Fig. 3, the strip being of substantially the same size as the envelop, so as to effectively cover and protect the seam or joint thereof, and having opposite end aps 8 and 9, provided upon their inner edges with the usual sealing-unas commonly employed in all envelops. This is the completed form of the wrapper ready for use.

In using the device-as, for instance, in mailing registered letters and the'corresponding cards-the letter or letters are slipped into the outer envelop through its normally open end, after which the opposite free end of the envelop is bent or turned over and inserted into the normally open end of the inner and larger envelop'2, as indicated in'Fig. 4 of the drawings,the envelop l containing the letter being pushed inwardly until it is wholly within the inner and larger envelop. The register-cards are then slipped into the inner envelop, between the back of the same and the inclosed' smallerenvelop, after which the end flaps 8 and 9 of the sealing-strip are IOO folded over and sealed upon the front of the larger envelop, saidl iiaps preferably overlapping, as shown in Fig. 5. It Will now be apparent that the envelop 2 is made slightly larger than the other envelop in order that the latter may be conveniently inserted into said larger envelop.

From the foregoing description it is apparent that the wrapper will plainly indicate that it has been opened, as it is impossible to gain 4access to the inner or inclosed envelop without tearing or otherwise damaging some part of the wrapper.

What is claimed is- 1. A mailing-wrapper, consisting of a pair of oppositely-disposed envelops of different sizes, each of which has only one open edge, the open edges of the envelops being arranged mutually adjacent and opposite, and there being a foldable connection between the said open edges of the envelope, and said connection being constructed to permit of the smaller envelop being folded over and inserted into the open edge of the larger envelop, and a sealing-flap upon thefree side of the Open edge ofthe larger envelop and adapted to close the Open edge of the latter envelop after the former has been inserted therein.

2. A mailing-Wrapper, comprising opposite envelops of diiferentsjzes, which are flexibly connected and have their adjacent connected sides normally open, said envelops being normally folded over upon the ieXible connection and lying back to back, with their open sides unobstructed and a sealing-strip applied to the outer side of the larger envelop and having opposite projecting terminal sealing-aps.

3. A mailing-wrapper, comprising a main blank,havingopposite sections, each of which is provided with opposite side flaps, and an outer end flap, each section having its flaps folded over and mutually secured upon the same side of the blank, whereby two envelope are formed having inner adjacent flexiblyconnected open ends, and a sealing-strip secured to that side of one of the lenvelops which is formed by the mutually-connected iiaps, said strip projecting in Opposite directions beyond the Opposite ends of the envelop and forming sealing-flaps.
